AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
240 PM EST TUE NOV 25 2025
SYNOPSIS
A WARM FRONT LIFTS NORTH ACROSS THE AREA TONIGHT, FOLLOWED BY A
COLD FRONTAL PASSAGE WEDNESDAY NIGHT. THE AREA WILL THEN REMAIN
IN BETWEEN STRONG LOW PRESSURE TO THE NORTH AND STRONG HIGH
PRESSURE TO THE SOUTH AND WEST FROM THANKSGIVING DAY THROUGH
EARLY SATURDAY. THE HIGH WILL BUILD IN FOR MUCH OF THE WEEKEND.
A COLD FRONT THEN IMPACTS THE AREA LATE IN THE WEEKEND INTO
EARLY NEXT WEEK.
NEAR TERM /THROUGH WEDNESDAY/
AN AMPLIFYING UPPER TROUGH ACROSS THE EASTERN HALF OF THE
COUNTRY WILL SEND A FRONTAL SYSTEM TOWARD THE AREA. RAPIDLY
DEEPENING LOW PRESSURE WILL LIFT ACROSS THE GREAT LAKES TONIGHT
INTO WEDNESDAY, SENDING A WARM FRONT THROUGH THE AREA TONIGHT
AND A COLD FRONT WEDNESDAY EVENING.
RAINFALL AMOUNTS CONTINUE TO TREND UP A BIT WITH FORECAST
AMOUNTS ANYWHERE FROM A FEW TENTHS ACROSS FAR WESTERN PORTIONS
OF THE LOWER HUDSON VALLEY, TO AROUND AN INCH ALONG THE COAST.
LIGHT OVERRUNNING RAIN WILL SPREAD INTO THE AREA FROM SW TO NE
LATE THIS AFTERNOON INTO THIS EVENING AHEAD OF THE WARM FRONT.
THERE COULD BE SOME POCKETS OF HEAVIER RAIN LATER IN THE NIGHT
AS THE AIRMASS DESTABILIZES SOME AHEAD OF THE NOSE OF A 50 KT
LLJ APPROACHING FROM THE SOUTH. HOWEVER, NOT EXPECTING
THUNDERSTORMS AT THIS TIME.
THE RAIN LOOKS TO COME IN 2 WAVES, FIRST WITH THE AFOREMENTIONED
WARM FRONT, THEN WITH CONVECTION MOVING OUT OF THE TN VALLEY
LATER TONIGHT. THIS WILL FOLLOW NOT TOO LONG AFTER THE WARM
FRONTAL RAINS. CAMS ARE ALL LOCKING INTO THIS AREA AS WELL AS
THE 12Z GFS AND NAM. THE GFS KEEPS THE AREA TO THE SOUTH, SO
THERE REMAINS SOME UNCERTAINTY WITH THE SECOND ROUND. NBM RAIN
CHANCES HAVE TRENDED UPWARD. THE BEST CHANCE AT THIS TIME IS
ACROSS EASTERN LI AND SE CT. HOWEVER, SHOULD THIS TREND
NORTHWARD CONTINUE, CHANCES WILL INCREASE ELSEWHERE. FOR THE
REMAINDER OF WEDNESDAY, THERE COULD BE SCATTERED SHOWERS IN THE
WARM SECTOR AHEAD OF THE COLD FRONT.
PATCHY FOG IS ALSO LIKELY TONIGHT AND COULD BE MORE EXTENSIVE
ACROSS THE INTERIOR WHERE WINDS ARE FORECAST TO BE LIGHTER.
SOUTHERLY WINDS MAY GUST UP TO 20 MPH ALONG THE COAST THIS
EVENING, HOWEVER, A STRENGTHENING INVERSION WILL LIKELY LIMIT
THE POTENTIAL AS THE NIGHT PROGRESSES. WINDS WILL THEN VEER TO
THE SW BEHIND THE WARM FRONT.
TEMPERATURES WILL DROP LITTLE IF ANY THIS EVENING, THEN START
TO SLOWLY RISE THROUGH THE NIGHT WITH THE APPROACH OF THE WARM
FRONT. HIGHS ON WEDNESDAY WILL BE UP AROUND 60, WHICH IS ABOUT
10 DEGREES ABOVE NORMAL.
SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/
COLD FRONT MOVES THROUGH DURING THE EVENING HOURS WEDNESDAY
WITH A CHANCE OF SCATTERED SHOWERS. STRONG COLD ADVECTION WILL
THEN FOLLOW WITH GUSTY WEST WINDS UP TO 30 MPH. THESE WINDS
WILL CONTINUE THROUGH THURSDAY NIGHT WITH CONTINUED COLD
ADVECTION AND CYCLONIC FLOW. WINDS LOOK TO FALL SHORT OF
ADVISORY CRITERIA AT THIS TIME. USED NBM 90TH PERCENTILE FOR
WINDS.
STRATOCU WILL LIKELY MAKE IT INTO AREA NORTH AND WEST OF NYC
THURSDAY WITH EVEN A FEW FLURRIES AND/OR A BRIEF SNOW SHOWER
GETTING INTO FAR NW PORTIONS OF THE LOWER HUDSON VALLEY IN THE
EVENING.
TEMPERATURES WILL DROP INTO THE 30S BEHIND THE COLD FRONT
WEDNESDAY NIGHT AND LIKELY GET KNOW HIGHER THAN THE LOWER TO MID
40S THURSDAY. EVEN WITH WINDS STAYING UP THURSDAY NIGHT (LIMITING
RADIATIONAL COOLING), MOST LOCATIONS WILL GET TO AT OR JUST
BELOW FREEZING BY DAYBREAK FRIDAY.
LONG TERM /FRIDAY THROUGH TUESDAY/
KEY POINTS:
* WINDY CONDITIONS CONTINUE THROUGH FRIDAY NIGHT, WITH THE PEAK
BEING FRIDAY. WIDESPREAD GUSTS UP TO 35-40MPH ARE POSSIBLE, WITH
ISOLATED GUSTS UP TO 45MPH.

HIGHS IN THE LOWER/MID 40S AND WIND CHILLS IN THE 30S.
* MAINLY DRY THROUGH AT LEAST THE FIRST HALF OF THIS PERIOD, WITH
CONFIDENCE INCREASING IN RAIN LATE IN THE WEEKEND INTO EARLY NEXT
WEEK.
A LARGE ANOMALOUS UPPER LEVEL LOW AND TROUGH WILL BE OVERHEAD TO
START FRIDAY. AT THE SURFACE, STRONG LOW PRESSURE WILL BE PASSING TO
OUR NORTH WHILE STRONG HIGH PRESSURE SETS UP TO OUR SOUTHWEST. THIS
PLACES THE AREA IN A TIGHT PRESSURE GRADIENT AND WILL BRING WINDY
CONDITIONS THROUGH FRIDAY NIGHT. PEAK GUSTS LOOK TO BE FRIDAY IN A
W/NW FLOW WITH DEEP MIXING. THE NBM AND EVEN NOW THE NBM90TH
PERCENTILE LOOK TOO LOW WITH WINDS GUSTS BASED LATEST MODEL
SOUNDINGS AND RECENT NBM VERIFICATION IN THIS TYPE OF REGIME. STILL
THINKING THE FORECAST CAN TREND UP A BIT MORE WHICH WOULD PUT THE
AREA CLOSE TO ADVISORY CRITERIA FOR FRIDAY. AT THIS TIME THOUGH,
ONLY ISOLATED GUSTS UP TO ADVISORY CRITERIA ARE EXPECTED.
THE HIGH BUILDS IN ON SATURDAY AND PASSES OVERHEAD SATURDAY EVENING.
A COLD FRONT THEN APPROACHES THE AREA AND WILL BRING THE NEXT
CHANCES OF RAIN LATE SUNDAY INTO THE START OF NEXT WEEK.
